Patel, who joined Tulchan in 2008 after a 15 year career in investment banking, will join TalkTalk in mid-November.
He replaces current investor relations director David Boyd who is understood to be leaving TalkTalk to pursue other opportunities.
TalkTalk's comms director Mark Schmid told PRWeek that Boyd’s ‘incalculable expertise’ had played ‘a big role’ in steering the company through its 2010 split from the Carphone Warehouse to become a standalone company.
The moves follows TalkTalk’s shake-up of its comms advisers last month, which saw it replace Citigate Dewe Rogerson with a consortium of Bell Pottinger agencies, including Pelham Bell Pottinger to support financial comms.
Citigate had formerly held the account, thought to be worth £500,000 a year, for over a decade.
Schmid added: ‘Since our demerger we have been establishing ourselves as a separate entity and have looked to ensure we have the right people on board to take us to the next phase of the company’s development.’
Before moving into financial PR, Patel held senior positions at HSBC, Merrill Lynch Europe and NM Rothschild & Sons. At Tulchan, Patel worked on accounts including Legal & General, New Look and Enterprise Inns.
Andrew Grant, founder of Tulchan, commented: ‘We have enjoyed working with Mal and he has all the skills to make this new role at TalkTalk a success. He leaves with all of our best wishes.’
